8 XXX : normalnudes

would have guessed 26 maybe, not 41. holy moly.
looks normal to me, and for 41, amazing!
If you put your knees together, what happens to the gap? There really isn't anything to worry about with that cute butt. I didn't notice the indentation until I reread your subject. But, dat gap? Hhhnnnngggg! Love it!
You have the butt of a much younger woman. Be proud! You look like you have a very lean body type which I bet is super attractive. I don't think the spot at the top is unattractive or attractive... it just is. Everyone has parts of them that "just are." It looks like it still would have some curve from the side. Are you small up top, too? Your body is probably very balanced and attractive :)
me: F/45. you: omg girl, dat ass. dat ass is legitimately really quite excellent. i am doing a golf clap for it. nicely nicely!
